That's one of the things that bothers me about skating. An outcome in a sport should never be influenced by location but that's skating for ya.
Is it really? Or is that just a persistent myth.? Why would judges from other countries do such a thing? There are advantages to skating on home turf, but I really don't think they have much to do with the judging. Scientific studies about this have been done in other sports (team sports), I wish someone would do one in skating.
